1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

In excitable cells, voltage-gated sodium (Na(V)) channels activate to initiate action potentials and then undergo fast and slow inactivation processes that terminate their ionic conductance. Inactivation is a hallmark of Na(V) channel function and is critical for control of membrane excitability, but the structural basis for this process has remained elusive. Here we report crystallographic snapshots of the wild-type Na(V)Ab channel from Arcobacter butzleri captured in two potentially inactivated states at 3.2 Å resolution. Compared to previous structures of Na(V)Ab channels with cysteine mutations in the pore-lining S6 helices (ref. 4), the S6 helices and the intracellular activation gate have undergone significant rearrangements: one pair of S6 helices has collapsed towards the central pore axis and the other S6 pair has moved outward to produce a striking dimer-of-dimers configuration. An increase in global structural asymmetry is observed throughout our wild-type Na(V)Ab models, reshaping the ion selectivity filter at the extracellular end of the pore, the central cavity and its residues that are analogous to the mammalian drug receptor site, and the lateral pore fenestrations. The voltage-sensing domains have also shifted around the perimeter of the pore module in wild-type Na(V)Ab, compared to the mutant channel, and local structural changes identify a conserved interaction network that connects distant molecular determinants involved in Na(V) channel gating and inactivation. These potential inactivated-state structures provide new insights into Na(V) channel gating and novel avenues to drug development and therapy for a range of debilitating Na(V) channelopathies.
